What type of colors do electronic devices such as smartphones and TVs generally use?

Electronic devices like smartphones and TVs utilize additive colors. This color model operates on the principle of combining light to create a wide spectrum of colors. The primary colors in the additive color model are red, green, and blue (RGB). When these colors of light are mixed at various intensities, they can produce different hues. For instance, when red and green light mix, they create yellow, while combining all three primary colors in full intensity results in white light.

Additive color mixing is essential for electronic displays because they emit light directly. Unlike subtractive color mixing, which involves the absorption of certain wavelengths by inks and pigments, additive mixing allows devices to display vibrant colors by emitting light that the human eye perceives.

Being aware of this principle is crucial for graphic designers, especially when working with digital media, to ensure that the colors they choose appear as intended on screens.
